Patent GB-425581-A (GB)
Title: Improvements in or relating to the production of concrete structures
IPC: C04B41/48
Filed: 1934-10-04
Abstract: The moist condition of concrete is prolonged, during the setting and hardening period, by sealing the surface with a film deposited from an aqueous dispersion of or containing rubber.  If it is desired to remove the film eventually, the surface may be provided, prior to the deposit of the rubber film, with a layer of an inert granular material, e.g. barytes, clay, talc.  The granular material may be applied as a separate coating or together with the rubber by applying a non-viscous dispersion of rubber heavily compounded with the granular material which sinks through the wet rubber layer before drying and forms the desired layer.  A deposit of approximately 1 to 3 ozs. of rubber solids per square yard of concrete surface forms a satisfactory seal.  Specification 291,784*, [Class 22], is referred to.

Title: Fractionating solution containing more than one solute
Inventor: CREWSON GEORGE GRANT
IPC: B01D9/00
Filed: 1955-10-07
Abstract: <PICT:0785660/III/1> In a method of fractionating two or more solutes from a solution, solid and liquid phases of the solutes in a common solvent medium are established and the solid and liquid phases are moved countercurrent to each other, the common solvent being introduced into that end of the medium toward which the solid phase tends to move to provide a concentration gradient in the liquid phase of the solutes with respect to the common solvent, and solid phase enriched in one of the solutes is removed adjacent the place of introduction of the solvent while the liquid phase is removed from the end of the medium opposite that from which the solid phase is removed.  A solution, saturated or at high concentration, of potassium persulphate and ammonium persulphate in water or in aqueous sulphuric acid, is introduced by an inlet 18 (Fig. 1), to a tube 16 which has a portion 10 cooled by cooling medium in a jacket 12 to initiate crystallization of the salts.  Crystals may be removed from surface 10 by means of a scraper.  Crystals of both salts form and settle down the tube 16, building up a loose mass of crystals which occupies the full height of tube 16.  The solvent, i.e. water or aqueous sulphuric acid, is introduced by an inlet 19 and flows gradually upwards through the mass of crystals establishing a concentration gradient as it dissolves some of the descending salts, particularly ammonium persulphate which is more readily soluble. Crystals are constantly removed from the bottom of the mass through an outlet 21 while fresh crystals are supplied to the top of the loose mass.  The crystals are removed by outlet 21 as a slurry, liquid being recirculated by a pump 30, and consist almost entirely of potassium persulphate.  A solution of ammonium persulphate containing almost no potassium persulphate is removed by an outlet 11.  Instead of introducing a solution of the two salts by inlet 18, the salts may be introduced in crystal form to the medium in tube 16, in which case the cooled portion 10 is not required.  The lower end of tube 16 may be heated or cooled by circulating a medium through a jacket to maintain a temperature at which the difference in solubilities of the salts is most pronounced.  Other salts mentioned which may be separated are barium and lead nitrates.

IPC: G08C19/48
Filed: 1957-09-11
Abstract: 860,120. Control of two motors. KETAY Ltd. Nov. 17, 1958 [Sept. 11, 1957], No. 28699/57. Class 38 (3). [Also in Group XXXV] Two-phase valve-actuating motors 5, 6, are kept in angular correspondence by coupling the motors to synchronizing machines, the rotor 7 of the transmitting-machine being coupled to the spindle of valve 1 and its stator 9 connected to the stator 10 of the receiving-machine. The rotor 8 of the latter is coupled to the spindle of the valve 2 and provides an output voltage proportional to the angular displacement between the two machines, the phase of this voltage being dependent upon the direction of displacement. The output voltage is supplied to amplifier 11 connected to transformer 12 having secondary windings 13, 14, which are respectively in series windings of the motors 5, 6, but are arranged in opposite senses. Thus, when the amplifier provides an output signal, one motor will accelerate and the other decelerate or reverse its direction of travel so as to bring the two valves into a synchronous position. The synchronizing machines may be replaced by potentiometers, and the motors may be of the D.C. type with subsidiary field coils fed from the amplifier.

Title: Compounds containing phosphonitrilic rings, and polymers thereof
IPC: C08G79/02
Filed: 1965-07-07
Abstract: A polymer containing the repeating units <FORM:1094543/C3/1> and <FORM:1094543/C3/2> wherein <FORM:1094543/C3/3> represents a triphenyltriphosphonitrile ring having 3 open valencies, and having a moleular weight of from about 3000 to about 5000, may be obtained by heating a compound of the formula <FORM:1094543/C3/4> wherein o represents a phenyl group and R is a C1- 3 lower alkyl group prepared from the corresponding phosphonitrilic triamine, HCHO and an alkanol at a temperature of from 190 DEG  C. to 280 DEG  C.  The heating is suitably continued for a period of from about 1 to about 2 hours and the resultant polymer, which has a molecular weight of from about 3000 to about 5000, is subsequently cured at a temperature of about 230 DEG  C. to about 280 DEG  C., preferably in the presence of hexamethylenetetramine.  From about 1 to about 4 parts by weight of a filler e.g. an inorganic material such as particulate silica, glass wool, vermiculite, abestos or metal chips, may be incorporated in the resins and the filled resin is heated at a temperature of from about 230 DEG  C. to about 280 DEG  C. for a period of from about 2 to 10 hours under a pressure of about 70 to 200 kg/cm.2.  The filled resins may then be subsequently fired at temperatures of 800 DEG  upwards to yield ceramic type materials.ALSO:The invention comprises compounds of the general formula <FORM:1094543/C2/1> where R is a C1- 3 alkyl group #f represents a phenyl group.  They may be prepared by reacting cis and/or trans-2,4,6-triphenyl, 2,4,6-triaminocyclotriphosphonitrile with formaldehyde (which may be obtained from a formaldehyde-yielding compound) in the presence of a C1- 3 alkanol at a temperature of 60-100 DEG  C. The reaction is generally effected by admixing from about 3 to about 4 moles of formaldehyde (or the equivalent amount of a formaldehyde yielding compound such as paraformaldehyde or hexamethylene tetramine) with each mole of 2,4,6 - triamino - 2,4,6 - triphenyltriphosphonitrile in a C1- 3 lower alkanol, the latter preferably being present in an amount of from about 10 to about 100 parts by wt. per part by wt. of reactants, adjusting the pH to about 5 to 8 with an inorganic base, e.g. NaOH, and refluxing the mixture for a period of from about 1 to about 3 hours.  The phosphonitrilic starting material may be obtained by reacting phenyltetrachlorophosphorane with NH4Cl in the presence of an inert solvent at elevated temperatures, e.g. from about 130 DEG to 160 DEG  C., and ammoniating the resulting product with an excess of NH3 at about room temperature and preferably in the presence of an inert solvent, e.g. chloroform.

A carburetter has an atomising jet adjacent the edge of an opening leading to the engine, an apertured throttle valve moving across the opening to open and close the same, and adjacent the nozzle a baffle member between which and the carburetter casing the throttle valve moves whereby as the aperture in the valve passes into and through the space between the baffle and casing during the opening and closing movements the direction of the air stream relative to the jet is varied to vary the suction created at the jet and thus vary the amount of fuel drawn therefrom. As shown a float chamber 2 is located in the induction passage 1. Mixture formed by air which enters at 22 and fuel from a nozzle 4 passes to the engine through an opening 5 which is controlled by means of a shutter 6 operated by a Bowden cable. When the shutter is closed air can flow between the casing and a baffle 8 to reduce the suction on the nozzle 4. The shutter includes preferably at the top a slow running slot 12. An air passage 14 leads into the passage 9 and bearings 16 for the shutter 6 by which it turns on a stud 15 extend beyond the stud 15 and control additional air by covering or uncovering the passage 14. When the shutter is opened the passage 14 is gradually closed. A cover 21 is detachably held by springs snapped on to it and when it is removed the float chamber can be removed without the use of a tool. The float may be depressed by a plunger 17 which also closes the vent hole 19.

Abstract: 676,242. Baling-press. HANSEN, H. S., and COOPER, D. W. C. Nov. 11, 1949, No. 28935/49. Class 94(i) A press for hay and the like, having a baling compartment, wherein material to be compressed is subjected to pressure by operation of a plunger in said compartment and also to pressure by lateral contraction of the latter, is characterized by the provision of means adapted for operation by material being compressed under the action of the plunger to bring about the contraction of said compartment. Hay, pushed through a baling compartment comprising a fixed base plate 2, and an inwardly movable top plate 1 and sides 3, 4, engages a spiked wheel 6, projecting through a slot in the top 1, to turn, through clutch means 21 and chain 9, a shaft 8 which winds up the rope of block and tackle means 10; alternatively the rope may be secured to a rail co-operating with a gear on the shaft 8. The lower block of the means 10 is secured to the base plate 2 and the upper block to the top plate 1 and the sides 4 are connected by toggle links 5 to the top and bottom plates so that rotation of the wheel 6 causes downward movement of the top plate 1 and inward movement of the sides 3, 4. This contraction is stopped when the friction of the hay being forced through the baling compartment is sufficient to slide a plate 11, mounted beneath the top plate 1, against the action of a spring 14 thus moving lever means 17 to disconnect the clutch 21. Pawl means may be provided to prevent reverse' movement of the wheel 6.
